Gamepad for a Motorola Droid Pro smartphone at all possible?

After seeing the Game-Gripper for various keypad smartphones, I wanted to have a gamepad for my phone as well. but i own a Motorola Droid Pro from Verizon and the screen and keyboard aren't right for some decent widescreen gaming. I dont think the game-gripper company makes pads for this kind of phone, so does anyone have any ideas on how i could either get or make a gamepad for this phone?
